Abatement of Polar Organics in Natural Wetlands and Rivers. Analitycal Methods

2001

Headley, J. (National Water Research Centre, Cairo (Egypt)) | Tawfic, T. A.

Here are described three innovative and complementary methods for the characterization of polar organics in natural waters. A simple and rugged GC/MS procedure is shown to be well suited for the determination of sulfolane, (tetrahydrothiophene 1,1-dioxide, C4H8O2S; a water miscible chemical used in the sweetening of sour-gas) a compound that is known to be readily sequested by wetland vegetation. In contrast, LC/MS employing electrospray ionization is ideal for the quantification of two other classes of polar chemicals, namely (a) alkanolamines in vegetation and (b) mixtures of naphthenic acids in natural waters in oilsands regions of Northern Alberta, Canada. The modem techniques take advantage of quite simple extraction procedures, with no need for derivatization steps and exploit the polar nature of the chemicals to separate the analytes from high back ground non-polar components. For the alkanolamines, MS/MS is a prerequisite for obtaining diagnostic product ion scans of the molecular ion formed under soft-ionization conditions.
